AI code review has moved from a novelty into a standard part of the pull-request workflow at many teams. Three real, current products dominate the conversation: CodeRabbit, a dedicated PR-review bot; Qodo, a broader agentic developer platform; and GitHub Copilot’s built-in code review and Autofix features for teams already paying for Copilot.
At a Glance
| Tool | Model | Entry price |
|---|---|---|
| CodeRabbit | Dedicated PR review bot | Essentials: $24/user/mo, no permanent free tier |
| Qodo | Agentic review (Qodo Merge) + broader dev platform | Credit-based, $0.012/credit; no permanent free tier |
| GitHub Copilot code review/Autofix | Bundled into Copilot | Included in Pro ($10/mo), Pro+ ($39/mo), Max ($100/mo) |
Short Verdict
If you already pay for GitHub Copilot, its built-in code review (generally available since April 2025) is the lowest-friction place to start, since it adds no new vendor relationship. If you want a dedicated review bot with transparent per-seat pricing and features built specifically around pull-request review, security prioritization, and unit test generation, CodeRabbit is the more purpose-built option. Qodo offers the broadest agentic surface, combining review, rules, and IDE/Git integrations, but its credit-based pricing is less predictable and its branding has shifted across products (Qodo Merge, Qodo Gen) in ways worth double-checking before you buy.
CodeRabbit
CodeRabbit is a dedicated AI code review bot that runs against pull requests, the CLI, and IDEs. Its pricing: Essentials at $24/user/mo (1 repo, 5 reviews per developer per hour, 5 MCP connections, Slop Detection for flagging low-quality AI-generated PRs, Pre-Merge Checks, and Autofix); Team at $48/user/mo (adds unit test generation, Finishing Touches, Post-Merge Actions like changelog updates, and a prioritized review queue, covering 5 repos); Advanced at $72/user/mo (adds security-informed prioritization, Blast Radius/architecture-impact analysis, and continuous security monitoring, covering 10 repos); and Enterprise by custom quote with self-hosting and custom RBAC. CodeRabbit integrates with Jira and Linear on every tier and offers only a 14-day trial rather than a permanent free plan, aside from an unspecified exception for qualifying open-source projects.
Qodo
Qodo, formerly known as CodiumAI, sells its PR-review product under the name Qodo Merge through a credit-based Pro Team plan at $0.012 per credit, with pooled team credits translating to roughly 18-144 reviews per month depending on the pack purchased. Enterprise (30+ users) is sold by custom quote with SSO/SAML, audit logs, and bring-your-own-key or on-premises/air-gapped deployment. Like CodeRabbit, Qodo offers no permanent free tier, only a 14-day trial plus free access for qualifying open-source projects. One naming note worth knowing: Qodo’s older open-source test-generation tool, Qodo Cover, is explicitly marked unmaintained by its own GitHub repository as of mid-2025, with current test-generation capability having moved into the “Qodo Gen” IDE extension instead.
GitHub Copilot Code Review and Autofix
Code review inside GitHub Copilot went to public preview in February 2025 and reached general availability in April 2025. It’s included at no extra cost in the Pro ($10/mo), Pro+ ($39/mo), and Max ($100/mo) Copilot plans. GitHub does not publish a simple standalone price for Copilot’s code-review feature on its Business or Enterprise tiers in the same comparison table, so confirm current rates for those tiers through your organization’s GitHub billing rather than assuming a commonly-cited figure. Separately, Copilot Autofix generates one suggested fix per supported CodeQL code-scanning alert with an explanation, and these fixes don’t consume AI credits; a related “agentic autofix” feature that opens a draft pull request automatically does consume AI credits and Actions minutes. Autofix is free for public repositories; private or internal organization repos need a GitHub Advanced Security / Code Security license, priced separately from Copilot itself.
Pros and Cons
- CodeRabbit pros: transparent, predictable per-seat pricing; purpose-built for PR review. Cons: no permanent free tier; separate vendor relationship to manage.
- Qodo pros: broadest agentic feature set (review, rules, IDE integration); flexible credit packs. Cons: credit-based cost is less predictable than flat per-seat pricing; product naming has shifted and can confuse buyers.
- GitHub Copilot pros: zero extra tool to adopt if you already pay for Copilot; Autofix integrates natively with CodeQL scanning. Cons: Business/Enterprise code-review pricing isn’t clearly published; private-repo Autofix needs a separate Advanced Security license.
Who It’s a Good Fit For
Teams already paying for Copilot Pro or above should try its built-in review and Autofix first, since it costs nothing extra to turn on. Teams that want a dedicated, security-focused review bot independent of their AI coding assistant vendor should look at CodeRabbit for predictable pricing or Qodo for a broader agentic toolset.
Bottom Line
All three tools are real, actively developed products as of this writing, and none offers a permanent free plan beyond trials and open-source exceptions. The practical starting point is whatever you’re already paying for: Copilot users should flip on its review and Autofix features before adding a second vendor, while teams not using Copilot should compare CodeRabbit’s flat per-seat tiers against Qodo’s credit-based pricing based on how predictable they need their monthly bill to be.
FAQ
Is Qodo Cover still Qodo’s test-generation product?
No. Qodo Cover’s GitHub repository is marked unmaintained as of mid-2025; current test-generation capability lives in the “Qodo Gen” IDE extension instead.
Does Copilot Autofix cost extra?
Fixes for CodeQL code-scanning alerts don’t consume AI credits. A separate “agentic autofix” that opens a draft PR automatically does consume AI credits and Actions minutes, and private-repo use requires a GitHub Advanced Security license.
Do any of these tools have a free tier?
None of CodeRabbit or Qodo offer a permanent free tier for commercial use; both offer time-limited trials and exceptions for qualifying open-source projects. GitHub Copilot’s review features require a paid Copilot plan.
